DISPERSE DYES FROM 2-HALO-4,6-DINITROANILINE AND
SELECTED 2(2'-ALKOXY-5'-ALKANOYLAMINOANILINO)ALKANES
Abstract of the Disclosure
Disclosed are disperse dyes comprising a chloro- or bromodinitro-
aniline azo moiety and a particular group of 2(2'-alkoxy-5'-alkanoyl-
aminoanilino)alkane couplers. These dyes give exceptional color depth
and brightness, shade permanency on heat setting, build, leveling, barr?
coverage, dye exhaustion and dyeing rate on fibers of polyester, cellulose
acetate, cellulose triacetate, and polyamide (nylon) over widely varying
dyeing conditions of, for example, temperature and pressure. The dyes
exhibit blue shades with excellent colorfastness properties on polyester
fibers and have excellent dyeability by heat fixation (Thermosol) or
exhaust (boil and pressure) methods of application on this substrate.
Uniform dyeability under a wide variety of conditions is an exceptional
feature of the present dyes.
